Dang man, it depends on what your GPA, EC's, Personal Statement etc are like. I did terrible on QR 14, and for some schools its below the cutoff others its not. Honestly, after I took it I felt like I fell short in BIO as I bet you do too, no offense I am just sure that you worked so hard and felt like the bio was very very random and does not reflect your knowledge of the subject. At least I did. So I hated studying for the DAT, but if you have time before you apply whenever that may be you may want to retake or just apply and see what happens. I did and so far its working out ok, I wish I had an interview from every school, but its not reasonable. You did very very well, so if those were my scores I would not retake. But that is just my honest opinion. A 20AA and 19 TS are great.
